You’ll find that we have created in-depth reviews for each of these top online casinos, which are well worth reading if you’re interested in joining. We’ve covered a range of important details for each, including its licensing and security, its game options, its promotions and bonuses, and accepted payment methods.
The best IGT casinos also offer plenty of other alternatives to the Triple Diamond casino game, whether you’re looking for classic-style or modern video slots. You’ll also be able to find table games and real dealer titles from some of the world’s best developers as well as sports betting platforms.
Before we get too deep into this review, we want to give you the chance to play a demo version of the game. This is a great opportunity to get a feel for the game and to see if it suits your needs. It’s essential to try free demos for a arcade-style game such as this, as many readers may prefer more modern slots with plenty of special features.
Although you won’t be able to win any real money, there are no financial risks involved with playing demo versions, so you’ve really got nothing to lose. If you like the demo, then the real money version offers exactly the same gameplay. All of our top US Triple Diamond casinos offer the real money version.
The Triple Diamond online slot was released in 2015 by IGT, an international software developer with decades of experience in creating land-based and online video slots. This game is straightforward in its design and uses a classic fruit-machine set-up of 3 reels by 3 rows.
As is the case with these types of games, the slot does not have any special features. Instead, it’s just a matter of setting your bet and clicking spin. Wins are paid out when three of any symbols land across one of the 9 fixed paylines.
| ▶️ Type of Slot | Video Slot |
|---|---|
| ▶️ Payout Rate | 95.06% |
| ▶️ Theme | Classic style |
| ▶️ Reels | 3 |
| ▶️ Rows | 3 |
| ▶️ Paylines | 9 |
| ▶️ Free Spins | No |
| ▶️ Betting Limits | $0.25 – $900 |
| ▶️ Bonus Round | No |
|---|---|
| ▶️ Progressive Jackpot | No |
| ▶️ Multiplier | Yes |
| ▶️ Gamble | No |
| ▶️ Autoplay | Yes |
| ▶️ Quick Spin | No |
| ▶️ Coin Levels | 1 |
| ▶️ Adjustable Paylines | Yes |
The game has a striking neon purple, blue, and orange color scheme that evokes arcade games of the 80s. There are only 6 symbols. In ascending order of value, these are the ANY BAR, the BAR, the DOUBLE BAR, the TRIPLE BAR, the 7, and the TRIPLE DIAMOND.
The higher the value of the symbol that lands, the larger the multiplier. Of these, the TRIPLE DIAMOND is the only symbol that will award a payout when only one lands on the reels. You can bet anywhere between 25c and $900, making it one of the online slots with broad appeal.
The Triple Diamond slot’s RTP is 95.06%, which indicates that this is a fair slot. While we prefer to see online slots with RTPs of around 96%, it’s common for arcade-style games to have lower RTPs, and they often get lower than this game’s payout rate.
The title also has a low volatility. This means that while payouts will be regular, these will often be in small values. The best thing you can do is to land three TRIPLE DIAMOND symbols across the reels, as this will offer a 1,199X return on your stake.
| RTP Rate: | Highest Paying Symbol: | All Symbols: | Paylines: | Max. Win |
|---|---|---|---|---|
| 95.06% | Triple Diamond | 6 | 9 | 1,199 x stake |
Therefore, if you make the maximum bet of $900, the maximum possible payout is over $100,000. While this is a very high number, there are other games with payouts of over 10,000X your stake. Additionally, games like Jack and the Beanstalk have a higher theoretical return-to-player rate.
When you sign up for a new online casino, you’ll be entitled to receive bonus funds or free spins. You will be able to spend these on this game, though you won’t be able to wager the maximum stake. Overall, we are satisfied with the RTP rate of this game, as this is what we’d expect from a classic-style game.
Classic-style slots do not appeal to everyone, due to the fact that they usually don’t offer special features. This means that there is no way to trigger free spins or any other special multiplier rounds. Instead, the main reels benefit from a boosted general payout rate and higher occurrence of payouts than modern-style games.
If you’re used to playing classic games then you’re bound to enjoy this game, as it doesn’t deviate much from the format. For many readers who prefer modern variants with interesting bonus features, this game will likely be a huge turn-off. If you’re looking for something in the middle, we recommend you try the simple yet hugely successful Starburst slot or the feature-rich Hotline slot.
As a fan of old-school classic-style slots, I thoroughly enjoyed this game. With nine fixed paylines and 6 symbols to keep track of, this is a no-frills yet easy-to-follow game that is fast-paced and exciting. The RTP rate is relatively fair for this style of game, and the low volatility rate means that payouts are awarded frequently.
